Huawei HCIE-Datacom V1.0 Sample Questions (Q273-Q278):

NEW QUESTION # 273
MSTP switches treat RSTP switches as MSTP domains, MSTP, which are formed by a single switch The interchange resolves the RSTBPDU to MSTBPDU, where IRPC is 0

A. True
B. False

Answer: A

NEW QUESTION # 274
OSPFv2 is an IGP running on IPv4 networks, whereas OSPFv3 is an IGP running on IPv6 networks. OSPFv2 and OSPFv3 have similar LSA types, but their LSA functions are slightly different. Which of the following is not an OSPFv3 LSA type?

A. Network-LSA
B. Router-LSA
C. AS-External-LSA
D. ASBR-Summary-LSA

Answer: D

Explanation:
Comprehensive and Detailed
OSPFv2 (for IPv4) and OSPFv3 (for IPv6) LSAs differ in function and naming conventions.
Key Differences in OSPFv3 LSAs:
OSPFv3 does not use ASBR-Summary-LSA. Instead, it introduces new Inter-Area Prefix LSAs (Type 3) and Inter-Area Router LSAs (Type 4).
OSPFv2 ASBR-Summary-LSA (Type 4) is replaced in OSPFv3 by Inter-Area Router LSA (Type 4).
OSPFv3 LSA Types:
✔ Router-LSA (Type 1) - Describes router interfaces and links.
✔ Network-LSA (Type 2) - Describes broadcast network links.
✔ Inter-Area Prefix LSA (Type 3) - Replaces Summary LSAs for routes.
✔ Inter-Area Router LSA (Type 4) - Replaces ASBR Summary LSAs.
✔ AS-External LSA (Type 5) - Describes external routes (same as OSPFv2).
Since ASBR-Summary-LSA (Type 4) does not exist in OSPFv3, the correct answer is A.

NEW QUESTION # 275
0SPFV2 is running on the IPV4 network IGP: OSPF3 is running in the IPV6 network, OSPF35 OSPFV2 has the same message type. Includes hello messages, DOD messages, LSR messages, LAU messages, and SAX messages about OSPP The following statement is correct?

A. OSPFv3 uses the link-local address as the source address for sending packets, which can be forwarded outside the range of the originating link
B. The hello packet of OSPFv3 carries the IPV6 address prefix of the router interface
C. OSPFv3 sends OSPFv3 packet using the IPV6 multicast addresses FF02::5 and FF02
D. OSPFv3 uses the authentication field of the packet header to complete the packet authentication

Answer: C

NEW QUESTION # 276

A. Inter-AreaPrefirLSA also contains LinkLocal information file
B. Inter-AreaPrefix-SA's LinkStatelD contains the prefix
